The Effect Of Different Amounts Of Vinegar

In some cases, reactions will not respond to heat and chemical change. Undesired side products may be produced as well in experiments such as this. Mechanical errors play as role as well when products are loss due to improper weighing, transferring, and drying methods. These reasons will also affect the melting range of the product as well. The end result for this experiment will be the production of acetaminophen, a fever reducing and pain-relieving compound, which is use in creating

he experimental variable in this experiment was the changing number of Alka Seltzer tablets that were put into the 250mL beaker of vinegar. Some of the control variables in this experiment were that the same beaker and thermometer were used for each trial, the same type of vinegar and Alka Seltzer were used for each trial, and the same amount of vinegar. The original Hypothesis was that more Alka Seltzer would increase the temperature of the vinegar was not correct. After analyzing the data it can be seen that for the first trial the temperature did not change as it stayed at 24 degrees Celsius before and during the reaction with 1 tablet, also for trial two with two tablets the temperature stayed the same at 23 degrees Celsius and did

In the lab the total volume of solutions used is kept constant in all the trials so that the temperature change remains directly proportional to the amount of reaction that occurs as well to the extent of the reaction.

Observations: During the experiment, bubbles were present from the water in the electric water baths that were set at temperatures of 50 degrees Celsius and 60 degrees Celsius. This is because the water has passed its boiling point and began to boil. The glucose powder had a white color. The yeast powder had a mild yellow color. When the glucose solution was mixed with water, it gave a clear color. When glucose solution was mixed with the yeast, it produced a murky yellow color. Bubbles also arose when CO2 was being lost in the experiment under each desired temperature.

The purpose of this experiment was to mix Alka-Seltzer with Hydrochloric acid in order to analyze Sodium Bicarbonate as an active ingredient in the Alka-Seltzer. The mixture will contain hydrochloric acid to only see the composition of Sodium Bicarbonate in the tablet once it reacts. The amount that reacted allowed us to determine how much of it is present in the tablet. The amount of sodium bicarbonate will be measure by using the ideal gas law PV=nRT. The experiment will be conducted in the lab, therefore we are going to use room temperature which ranges from 15 to 26 degrees celsius. At room temperature pressure ranges from 12.8 to 25.0 millimeters mercury according to its corresponding room temperature.In the ideal gas equation R is 0.08206latm/mol k which is a constant. Once we have those values we can calculates the number of moles that reacted in the mixture by solving for the missing value. With the number of moles we are able to find the mass in grams which is what will potentially tell us the composition of Sodium Bicarbonate in a tablet of Alka-Seltzer.

Hypothesis: If the temperature increases, then rate of the chemical reaction will increase as well, and if the temperature decreases, then the rate of reaction will also decrease.

We were also able to conclude that when you combine equal parts of an acid and base you can expect to see a higher temperature change than you would if you added more parts of a base than a acid. Our reasoning behind this conclusion is that when we added 10 mL of both solutions that temperature increased by 5ºc, but when we added 15 mL of NaOH and only 5 mL of CH3COOH there was only a temperature increase of 3ºc. In correlation, we calculated that when you have equal parts of acid and base, the ΔHrxn will be higher than when you use more parts base than

Procedure: Filled each test tube with substances provided and subjected them to various conditions. These conditions included, heat, cold water, hot water, acid and basic additions and tested on litmus paper. The reactions were observed and documented at each step.

Discussion The purpose of this lab was to measure the mass of a solid reactant, in this case, NaHCO3, which is also known as baking soda, and to find the mass of the solid product NaCl (salt) as well. From there, the masses were to be converted into moles and created into ratios that showed the relationship between the reactants and products. That information was then compared to the theoretical data in order to check its accuracy and reveal the significance of mole ratios in chemical reactions.. During the experiment, hydrochloric acid (HCl) was added to the baking soda in order to begin the reaction.

A chemical change can be caused by combining two compounds, such as baking soda (NaHCO3) and vinegar (CH3COOH). The change that is taking place is because of the chemical property of reactivity. When these two compounds react CO2 is produced. In this experiment we wanted to see how much baking soda, added to 10mL of vinegar, would cause a film canister rocket to shoot the farthest. I predicted that 10mL of baking soda would shoot the farthest because it would be equal to the amount of vinegar in the canister. The independent variable in this experiment was the amount of baking soda and the dependent variable was how far the lid would shoot.

The independent variable for this experiment will be the the temperature of the acids used for the reaction between the alka seltzer tablet. Four trials will be tested the temperature will be 25C, 45C, 65C, and 85C. Starting off the first trial will be 25 C (room temperature) and will increase each trial by 20C. Both the acids will have a molarity of 1 and the amount used for each of the trials is 20ml.

In this experiment, we investigate the change in temperature caused by adding a chemical substance into the water and dissolving it. The results recorded in the table below show that our hypothesis is correct.

This experiment was performed to determine the heat of neutralization between Hydrogen chloride (HCl) and Sodium hydroxide (NaOH). A temperature probe was used to measure the temperature of the reaction when the base (NaOH) was poured into the acid (HCl). The data was collected on logged on LoggerPro.

Rate of reactions play a vital role in real life situations. Everyday situations, such as cooking, require reaction rates to be increased. To bake some cookies, you place them inside an oven. But why is that? Well, placing the cookies in the oven speeds up the rate of the reaction by heating it up. When the cookies have more heat energy, they cook faster. Additives may be added to foods to speed up the reaction. These are called catalysts. Likewise, we place milk in our fridges to slow down the reaction rate by removing heat and preventing the milk from going bad. This is because the milk would turn sour if we left it out near a window. (14)

If the temperature in the solution of the enzyme peroxidase increases, next the rate of peroxidase will also rise because the warmer the solution, the faster the molecules move, thus causing increased collisions between substrate and enzyme. If the temperature in the solution decreases, the rate of reaction will decrease because a colder solution forces molecules to move a lot slower, causing the amount of collisions between enzyme and substrate to decrease.
